Breaded or battered chicken in the shape of balls.
Very common in Canada, too.
It’s a staple of Chinese Canadian food. Usually sweet and sour chicken balls, but they’re also served with lemon sauce, pineapple sauce or honey garlic in some restaurants.
I took my Bay Area relatives for sweet and sour chicken balls in Calgary. They had never seen them before.
